Terracotta doesn't come before its color variations in creative

Can confirm

From now on, we only accept reports about "incorrect" creative inventory sort ordering if the items/blocks were added in the Nether Update (1.16) or later. All other issues will be closed as a duplicate of MC-1797, which has been marked as Invalid due to the fact it is seen as a feature request.
